The document discusses different types of language translators including compilers, interpreters, and assemblers. A language translator converts source code into object code that computers can understand. Compilers convert an entire program into object code at once, while interpreters convert code line-by-line. Compilers are generally faster but require more memory, and errors are detected after compilation. Interpreters are slower but use less memory and can detect errors as they interpret each line.

4. Why Language Translators?
 Computer only understands object code (machine code).
 It does not understand any source code.
 There must be a program that converts source code in to the object code
so that the computer can understand it.
 The language translator is one which does this job.
 The programmer writes the source code and then translator converts it
in machine readable format (object code).

7. Compiler
 Compiler is the language translator that converts high level
language code in to the object code (machine code).
 It converts the whole code at a time.

11. Difference between Compiler and Interpreter
Compiler
 It converts whole code at a time.
 It is faster.
 Requires more memory.
 Errors are displayed after entire program
is checked.
 Example: C, C++, JAVA.
Interpreter
 It converts the code line by line.
 It is slower.
 Requires less memory.
 Errors are displayed for every
instruction
interpreted (if any)
 Example: GW BASIC, Ruby, Python
